Get PriceGrinding: grinding all materials into required fineness by cement mill. Cement ball mill and vertical cement mill are two common types. Homogenizing: homogeneous kiln feed is the precondition of clinker production, so homogenization of raw materials guard a pass of cement plant
Get PriceThe liquid percentage at 1450 0 C can be estimated using the formula. % Liquid content (1450 0C) = 3.0 x A+2.25 x F+S. Where A=Al 2 O, F=Fe 2 O 3, S= MgO+K 2 O+Na 2 O+SO 3 In Clinker. The normal range of liquid phase is 22-27%. Burnability is a reference value for
Get PriceIn this stage, the cement clinker is added with an appropriate amount of the mixed material ,it is be ground to produce finished cement. The electric motor drives the disc through the reducer, and the hot air enters the vertical roller mill from the air inlet. The material falls from the feeding
Get PriceThe vertical pre-grinding mill makes use of pressing force and shearing force for material grinding. It offers better grinding results than roller mills. When used for cement raw material and cement clinker pre-grinding, the pre-grinding machine can increase production capacity by 100% and 50%, respectively, while reducing electricity
